BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 329,7i6, dated November3, 1885. Application filed May 7, 1885. Serial No. 164,674. (No model.)

To all whom it may concern: I

Be it known that I, HENRY F, KING, of Bellows Falls, in the county ofWindham and State of Vermont, have invented certain new and usefulImprovements in Butter-Yorkers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled inthe art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

My invention relates to that class of butterworkers in which thebuttermilk (or buttermilk and brine) is pressed out from the butter bymeans of a rolling pressure, the roller moving forward and backward in atray; and the leading feature of my invention consists in a specialconstruction of certain parts, as will presently appear, wherebyfriction is materially diminished, the machine is worked with much lesslabor, the roller-frame is betterkept to place and guided, and the wholeapparatus, when in use, made more firm and steady by the aid of anadjustable reach, and which also permits the folding of the entirestructure into a close compact form for transportation or shipment, orwhen to be laid away after use, and also permits the raising or loweringof the frame or table at will.

Figure 1 represents in perspective a butter worker embodying myimprovements; Fig. 2, a cross-section of the track for a retainer, Fig.2*, plan and edge views, enlarged, of one of the flanged rollers; Fig.3, the under side of the tray with the legs folded up; Fig. 4, aretainer forthree friction-rollers; Figs. 5 and 6 retainers adapted forfour friction-rollers, and Fig. 7 an under side of the tray with thelegs so arranged as not to overlap when folded up.

A is the supporting and adjustable frame for the tray B, and G theroller-frame carrying the roller D, the tray inclining, as usual, andhaving an outlet or outlets for liquid.

E is the retainer, by means of which the traversing arms F of theroller-frame are guided and kept to their proper course when the machineis in use. This retainer is shown in Figs. 1 and 4 as made triangular ortriarmed, the two lower arms, 9 g, and also the central and upper arm h,being furnished w1th I flanged friction-rollers i, which run upontrackIt may, however,,be adaptedfor four such flanged rollers,-as shown inFigs. 5 and 6 two for an upper track and two for the lower track.WVhether three or four flanged rollers housed the retainer is furnishedwith ,a cente ring or journal pin, 70, at its upper extremity, and bymeans of whichit-issuspended or hung on the traversing armof the frame,one ateach side of the tray. This secures a permanent relationshipduring the working of the machine between the roller-frame and theretainers, the journal-pins not only allowing any needed swinger play ofthe retainers to prevent the binding of the latter onthe tracks when inaction, but also permitting any needed rise and fall of the frame andits roller, and also preventing the frame becoming accidentally liftedoff the retainers, and requiring no auxiliary device to hold these partstogether. The flanges also compel. the retainers not only to keep theirplaceon the track, butalso hold the retainers to the frame. When butthree friction-rollers are used, I place oneon the upper or center armof the triangle, asshown in Fig. 1, and hang the triangles to theextremities of the traversing arms Fof the roller-frame, and I prefer insuch case to have each of the fric tion-rollers flanged at its innerside similarly to a car-wheel, and to have the upper and lower trackscorrespondingly plowed out, so that all the wheels, both upper andlower, may run on a flanged track. Such track may be very simply made ofa single strip of wood, having one side flanged at top and bottom, or oftwo pieces secured together side by side,one being broader than theother, and in either case being somewhat T-shaped in cross-section, asshownin detail, Fig. 2. It will be now evident that this constructionand arrangement of flanged rollers that is, two such lower rollers andone or two upper ones and the doubly-flanged track-afford the greatestassurance of keeping the parts to place, and that the triangulararrangement allows of the greatest freedom of movement and play, and theprovision of up per and lower rollers precludes any tendency;

to bind or tighten at any point. The construction is also simple andcheap. The retainereframes E, whether for three or morerollers, may becastin a single piece, and with pins or journals for the rollers made orcast integral with them. (See Figs. 4, 5, and. 6.) They may be hung by'means of their centering pins or journals k on metal pieces m, securedto the end of the roller-frame or di-,

rectly to the arms F, as may be most'con venient.

N N are the folding legs, which support the tray, being hinged thereto,as shown; but unless properly stayed or braced the tray would beunsteady and shaky when in .use, and if braced by a single piece orbrace would still be far from firm hence I have provided the followingdevice, which not only holds the whole firmly, but also has means forad-, justing it, so that the degree of tightening up may be controlled,as foundnecessary. To

each of the cross rods or bars 0 o of the legs;

I connect a strip orbar, 1), long enough to overlap each other,andfasten them firmly together at any point desired,the two con-'stituting what may be called an adjustable reach.

A simple and efficient meansfor fastening consists in slotting one orboth of the bars-p. near its inner end, andemploying an adjust= ingthumb-screw or pin, q, extending through both bars, and whereby,whenvthe legsare' placed the proper distance apart, they =maybeconnectedly held to that position by tightening up the screw or .pin. Athumb screw and nut, or any equivalent device, may be used for thispurpose. This adjustment of the:

lower ends of the legs nearer to orrfarther from each other serves alsoto raise or lower the practical height of the tray from the floor toadapt it and the roller-frame tothe height;- of the person working themachine. c

When the whole apparatus is to befoldedup and laid aside until againwanted for use, the bars p are loosened'from each other, the legs areturned inward, so'asto fold or lie against the under side of the tray,the bars 10.

also being similarly brought up against or parallel with the tray, thecrossbars 0 either turning in their bearings or the bars 10 turning onthese cross-bars for this purpose, or the bars pmay, if preferred, behinged to the crossbars to allow of this folding.

- Instead of the legs being arranged to lap,

(each'pair side by side at their ends when folded,) as shown in Fig. 3,they may, when short enough, be so applied to the under side of the traythat when folded against it their ends will abut or nearly touch eachother, as shown in Fig. 7.

I claimv 1. In a butter-worker, in combination with the roller-frame, apendent retainer having at its upper end a journal-pin and carrying,upper and lower anti-friction rollers adapted to run both onthe upperand lower surfaces of a trackrbar, as shown and described. 2. In abutter-worker, in combination with the rollerffr'ame, the pendentretainers provided each with the journal-pin k at its upper end and withthe upper and lower flanged friction-wheels, as shown and described, andthe tracks flanged on their upper'and lower sides, all. substantially asset forth.

3. In a butter-worker, incombination with the retainers provided withthe journal-pins k at their upper ends and with the upper and lowerflangedvwheels, the tracks, flanged as set forth, the pressure-roller,and the handles or frame for operating the same.

4. In combination with the tray of a butterworker, folding legsconnected to its under side, and the adjustable bars or reach p 1),connecting .the two sets of legs, and a screw or pinforadjusting andsecuring these bars one to the-other to determine the spread of the legsand to-firmly hold the tray to its desired position.
